White Plastic Bottle, 18/410, Glossy Golden White Pump, 100 ml

The white plastic bottle with a white and gold glossy pump combines a white 100 ml PET bottle with a pump that dispenses a small, consistent dose with every press. It suits liquid, free-flowing products that are applied in small amounts: facial serums, light emulsions, lotions, hand fluids, liquid cleansing products or oil serums. The set is declared suitable for contact with cosmetics, and the pump fits the neck of the bottle without any further adjustment.

The opaque white wall of the bottle hides the contents and limits the access of light. The bottle is therefore also suitable for formulations with more sensitive ingredients, for example vegetable oils prone to oxidation or vitamins. PET is lightweight and shatterproof, which you will appreciate when travelling, in the bathroom and when shipping finished products to customers. The glossy white and gold pump gives the set the look of a finished product without any further modification.

How the set dispenses

The pump draws the product through a dip tube that reaches the bottom of the bottle. One press dispenses approximately 0.14 ml, which corresponds to the amount for a single application of a facial serum or fluid.

Before first use the pump needs to be primed, that is, pressed several times until the dip tube and the mechanism fill with the product. Every pump with a dip tube behaves this way, and it is not a defect.

Nominal and total volume

The nominal volume is the amount the bottle is designed for under normal filling. The physical volume up to the neck is larger. The difference provides room for the dip tube and the pump mechanism, which takes up part of the space once screwed on, and for slight expansion of the contents with changes in temperature. Therefore, fill the bottle up to the nominal volume, not to the brim, otherwise the contents will overflow through the neck when the pump is fitted.

Suitable for products such as

• Facial and eye serums – a small dose corresponds to the amount for a single application, and the white wall protects active ingredients from light.
• Light emulsions and body lotions – free-flowing O/W emulsions are dispensed evenly and without hands touching the contents.
• Oil serums and blends of vegetable oils – the pump replaces the dropper where you need more than a few drops.
• Liquid cleansing products and micellar waters – for daily use in the bathroom, unbreakable PET is worthwhile.
• Samples and travel sizes – the 100 ml volume and the lightweight bottle are well suited to travelling.

Good to know

Before the first filling, we recommend rinsing the bottle, disinfecting it with isopropyl alcohol or ethanol and letting it dry completely. It is enough to rinse the pump and likewise let it dry. Residual water in the mechanism would otherwise dilute the first doses and burden the preservative system.

The pump is not a hermetic closure. Air enters the bottle with every press, so the contents need effective preservation unless the product is an anhydrous oil product. At the same time, the contents do not come into contact with fingers, which is an advantage over a jar.

PET tolerates water-based and emulsion formulations without problems. For anhydrous products with a high proportion of essential oils, for alcohol-based products or for formulations with solvents, we recommend testing the behaviour of the material and of the pump seal on a sample before filling an entire batch. PET is not suitable for hot filling, so let the contents cool before filling.

Only the white PET bottle on its own has a certificate for direct food contact; the pump does not. The set as a whole is therefore intended for cosmetics.

After thorough cleaning, the bottle can be reused. With the pump, reuse depends on whether the mechanism can be rinsed out completely. When you change the formulation, it is safer to fit a new pump. You will find closures with the same neck type as stated in the parameters, as well as other ready-made combinations, in the Handymade range. If you make your own combination, check the tightness and dispensing with your specific formulation.
